Kernrechtsfrage
Whether the federal complaint against revocation of a settlement permit was admissible and the applicable law was ANAG rather than AuG.
Extrahierter Entscheid
The public-law appeal was admissible, and the case was governed by the former ANAG.
Extrahierte Begründung
Cantonal final decisions on revocation of settlement permits are challengeable; because the relevant facts predated 1 January 2008, the old Foreign Nationals Act remained applicable.
